First, let's force the creation of the first mirrored volume (see Listing 2), which I've referred to as d1.

首先，我们强制创建第一个镜像的卷(请参见清单2)，我将其称为d1。

Note that this isn't a copy operation, as demonstrated by the fact that both d1 and d2 have the same identifier values, as returned by the built-in id() method.

注意，内置的 id() 方法对于 d1 和 d2 返回相同的标识符值，这说明这不是复制操作。

d1 2 3 And we can do that just going along, 3 d 1, 2 3, and the problem comes when we get to chromium here, which is instead of what we would expect, 4s23d4 we might expect to see 4 s 2, 3 d 4.

我们能做的就是继续，问题出现了,当我们来到铬元素时，它不是我们预期的那样，我们可能预期。

Then when I create the stock, here, I can pass it in, pass in d 1.

然后当我在这里创建stock的时候，我可以给它赋值，把d1赋给它。

And then I'll create this function, d1 this distribution d 1, which will, whenever I call it, give me a random, a uniformly selected value between minus and plus volatility.

然后我会创建这个函数，这个概率分布，每次我调用这个函数的时候，他会给我返回一个随机的，按照均匀分布,从正负浮动值之间选择的值。
